Bringing this back to Python a bit:

Red-Black trees are supposed to be slower than treaps on average, but
they're also supposed to have a lower standard deviation
Hi,
Thanks for the answer. I copy the solution here:
According to wikipedia: "The original structure was invented in 1972
by Rudolf Bayer and named "symmetric binary B-tree," but acquired its
modern name in a paper in 1978 by Leonidas J. Guibas and Robert
Sedgewick."

Hi,
It's not really a Python-related question, sorry for that. Does anyone
know why red-black trees got these colors in their names? Why not
blue-orange for instance? I'm just curious.
Thanks,

There a many ways to do this, here's one:
from collections import namedtuple
Tree = namedtuple('Tree', ['feature', 'children'])
t = Tree(1, [Tree('hello', []), Tree(3, [])])

Dear sir,
I am very happy to find this group.
Sir, i am new to Python. Currently i am working on text processing.
Can you give me some suggestions about Tree data structure
representation, where i require each node capable to handle: only one
child, or up to 3 children plus hold feature

I'm writing a Python graph library (called Graphine) that's
pretty easy to use and does what you want. It is pre-alpha
right now, but if you're interested please let me know- I'm
very interested in hearing outside opinions.

Tuples can be used as trees: you can let them represent
